Eddy-Current Coating Thickness Gauge

The eddy current thickness gauge generates a high-frequency electromagnetic field through the probe, induces eddy currents on the metal surface, and measures the impedance changes caused by the eddy currents to calculate the thickness of non-conductive coatings. It is used to detect coatings such as paint and plastic on metal substrates and to control coating quality in industries such as automotive and electronics.
Selection
When selecting, consider the type of base metal and coating characteristics, and match the probe frequency and measurement range. Focus on measurement accuracy and stability, and review the instrument calibration certificate. Evaluate operational convenience and environmental adaptability, ensuring the probe size is suitable for the shape of the measured object. Refer to industry application cases to verify suitability.
